To all whom it may concern:

Be-it'known th' t I, GEORGE G. CONTANT, residing of Manhattan, county and State of New York, have invented certain new and useful Powdered- Egg Products and Processes of Making the r Same,

' tion. i a I invention relates 'to powdered egg,

and the'object of-the invention 18' products,

of which the following is a spec1ficato reduceeggs to powdered, form without materially altering their-chemical composir; tionlor dietetic value. The resulting products have many advantagesover the original eggs, I in that they can be preserved indefinitely, and the expense oi shipment greatly reduced, not only;ibe'cause-v of the fact that the water of the eggs has been eliminated,

thereby dispensing withits transportation -butbecause of the'fact, also, that the ex pense of packing andicratingisobviated."' The powderedegg products are adaptedfor v in the manufacture of cake, pastry ,and drinks, as well as'for various other cul nary y'purposes.

In the process of making the products,

union has takenfpla'ce between them, possibly in the form-or a'saccharate of albumen or an albuminateof sugar. 7

- Inpractising theinvention, Iremploy any suitable former vacuum drier, one type of "which is shownin the accompanying draw-- ing, which "illustrates the apparatus invertical cross-section, It will be understood,

' however, that the process may be carried out cific one herein shown.

' the whites and yolks of the eggs are, prefer- 1 fably, first separated, and batches (of each k fope'rated' upon separately. ,yspeaking gener all the whites contain about two-thirds figlby weight, of water and one-third (t) I of'solids, and the yolks contain substantially ne-third (1}), by weight,-- of water 'and-twobirds a of solidsj, As'the composition of Specification of tetteralatent."

' Thewhites of the eggs are placed in a mixing tank A, providedwith agitators b, and the agitation continued until the product is. thoroughly uniform inconsistency and allthe customary product eliminated. During this agitation, it-is-very essential'that below the surface of the 'materialfin order to .'avo1d-'all Whipping'of the whites',-or convers on thereof into froth,- In this respect, my invention embodies apronounced ime, rare,

thus destroys its vitality.

After the agitating} operation described," toievery twenty, 20' pouhdfsof;the product thus produced I'add substantially five and twothirds1f(5%) pounds of sugar, and

The commingled' whitesand sugar are red irommixing tank A to a delivery tank B, whence they, pass througha pipe 0, controlled by a valve a, into a vacuum drier D. The vacuum. drier, embodies a casing e, which, in: order to permit of-jthe. drying r operation being obs'er ved ;1may ,be provided with glass panels 'f, lijiterior, of the casing isthe drying v 7 other heating, fluid is admitted 'rthrou'gh" pipe I as a is common inithis type offldrier.

"The apparatusis provided with-a knife or scraper k,*which removes the dried filnrl from the drum, whenceit is deposited in a small car m, which is runinto the casing of the drier and removed therefrom through a door n provided inthe end of casing D. I ooperate the drier under a very high vacuum, of say'twenty-seven (27 or twenty-eight (28)- inches, and, for this-purpose, the pipe 0 is connected with-any suitable exhausting apparatus. 1

The temperature of operation and the ro- 1 tation of drum 9 are so coordinated that the I film, upon its removal from the drum, con-- tainssubstantiallytwo per cent; (2%) of moisture, I findthat, operatin under these conditions,'the film can be rea ily removed from the drum and deposited in car-m in a continuous strip, the further eifect of the drying operation in the'ca'r operating to re-' move'the residuary two per cent.

The. yolks can .b treated, to-;all intentsand vpurposes, in substantiallythe mannerdescribed in connectionwith the treatment of: the whites, exceptthatithe speed of rotation of the drier, if the same size drum were used as fordry-ing the whites, would, naturally, be greater, in order to compensate forthe lesser quantity'ofwater in the yolks.
